A top Burundian general and right-hand man to President Pierre Nkurunziza was killed in a rocket attack on his car on Sunday, prompting fears of further instability in the crisis-hit country. Adolphe Nshimirimana was widely seen as the central African nation's de facto internal security chief and even considered the regime's number-two. Police and witnesses said General Nshimirimana's pick-up was hit by two rockets and sprayed with automatic gunfire in the capital Bujumbura on Sunday morning.
